Does light travel through air?
yes. that is why you are able to see objects. light reflects off objects allowing you to see.
What happens to the speed of the light as it travels from the air through the glass and then through the water?
Sound can travel as long as there is something for it to travel through. This could be a gas (such as air), a liquid (such as water) or a solid (such as a metal). In outer space there is no air for the sound to travel though, so astronauts can not talk with each other unless they use a radio. Radio waves and light waves can travel through space, that is why we are able…
"Wave length" is a measurement that describes a characteristic of a wave. If the wave is a mechanical one, like sound for example, it must have some kind of material to travel through. Air is a good one. If the wave is an electromagnetic one, like light or radio for example, it can travel through air, but it doesn't need anything to travel through.
because sound is the vibration of air molecules. since there is no atmosphere in space, no air exists, and so not sound can travel through it. light on the other hand is tiny particles called photons. these 2 not rely on the presence of air to travel from 1 point 2 another if you liked this answer, please recommend me :-)
